To all whom it may concern:

Be it known that I, FREDERIGKWV. RUBIN, a citizen ofthe UnitedSta'tes, and a resident of Indianapolis, county"of Marion, and State of Indianafh'ave invented a certain new and useful Sealing {Means for Doors, Windows, and the like and I do" hereby .declare that the (following 'is' a-full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like'lettersrefe'r to'lilie parts. i

This invention relates to adj ustable sealing means for doors, windows. and. the like, and is particularly designed .for use with the doors of drying. kilns, ordn places where the heat within the structure is sufliciently intense to warp the door of' the structure.

The prime feature of the invention is the provision of strips, preferably of metal, which may be placed end to end around the edges of the door frame.

A further feature of the invention is the provision of pliable sections of fabric and means for attaching the same along one edge of the metal strips so that the fabric will press against the face of the door and prevent air from entering the structure around the edges of the door.

A further feature of the invention is the provision of means for adjusting said strips v so as to positively force the fabric against the door regardless of how much out-of-true the door may be.

Afurther feature of the invention is the provision of means for holding all of the metallic strips in contact with each other end to end.

Other objections and advantages will be hereinafter more fully set forth and pointed out in the accompanying specification.

In the accompanying drawings which are madea part of this application, Figure 1 is a perspective view of a door casing and door such as is commonly used with drying kilns showing the improved sealing means applied thereto; Fig. 2 is a top plan view of two of the sections of the sealing device and Fig. 3 is an edge elevation thereof.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates the door casing which may be of the usual or any preferred construction, and 2 indicates the door which is preferably mounted upon rollers and slides lengthwise of the door casing when being opened or ofsthe door andthus detractfrom the efficiency of itheikiln. To :over-come'this obj 'ectionabl'e I feature, strips 1 3, preferably of metal are placed end to end around the edges of; the" .door; casing adj acent, which, the ,door moves, said strips being held in engagement "Wltllithfl .casingnby .means of; bolts 4, which :pro ect through elongated slots 5, in the strips 3 and into the adjacent bars of the door casing.

By providing the slots 5, the strips 3 may be moved bodily toward the surface of the door as shown in Fig. 1, to compensate for the warped condition of the door, and in order to prevent air from passingbetween the ends of the strips and also to hold said strips in engagement with each other, one end of each strip is provided with a curved recess 6 into which takes a curved projection 7 on the adjoining end of the next succeeding strip, the ends of the strips on opposite sides of the curved portions being inclined away from each other so that when two or more of the strips are moved inwardly and out of direct alinement with the remainder of the strips, the ends of the strips will not bind against each other.

The front edge of the strip 3 is provided with an offset 8 for the reception of binding sections or strips 9 preferably of fabric, such as canvas, said sections being formed by folding several strips of the canvas together and then clamping the same into the offset by means of plates 10 and rivets 11, a part of the binding sections or strips projecting beyond the mctalic strips 3 so that when it is forced against the face of the door it will yield and at the same time adhere closely to the surface of the door, thus completely excluding air from the kiln and to prevent air from entering between the ends of the fabric where the ends of the metallic strips come together, insert sections 12 of the same material from which the binding sections are made are introduced between the folds of the binding sections and project from the binding section of one strip into the binding section of the adjacent strip, thus forming a continuous strip of binding material.

In applying the strips'to use, the strips 3 are arranged around the frame 1 adjacent to the edge of the frame over which the .door extends after which the door 2 is closed and the strip 3 then adjusted toward the door until the binding materials at the edges of the strips are engaged with the surface of the door at all points around the frame.

- The bolts 4.- are then turned down and the strips 3 securely locked in'. their adjusted position. a

It will be noted that the binding sections 9 extend a distance beyond the strips 3 so a that the door will readily move to open or ing.

closed position although parts thereof will be nearer the edges of the strips than others, the fabric strips yielding sufficiently to permit the movement of the door without bind- In this manner, the air is entirely excopies of this patent may be obtained for cluded from the structure around the door frame, and should the door become warped in a new place or additionally warped, the strips 3 are to be readjusted to compensate for the curvature in the door.

The invention claimed is:

In a sealing means for closures, the combination with a casing, and a closure therefor, of a plurality of strips placed end to end and lying flat upon the casing, whereby heavy loads may be moved thereover wit out affecting said strips, one end of ea h strip having a curved recess and a projection on the opposite end of each strip adapted to interlock with the recess of the abutfive cents each, by addressing the Commissioner of Patents, Washington, D.
